All good, you'll get it soon enough, and it's worth it, got some great info.

Boots suggestions are the way to go and I'd personally add the snorkel to the 'as soon as $$ is available' list To quote from the reference doc:

"Engine Prptection:
Snorkel - Proably the most important item for any diesel engine.On a Patrol the air intake come from inside the left hand (passenger) side guard. As you drive the dust that is stirred up from the front tyre is sucked into the guard and into the filter thereby blocking it quickly. Diesels do not like water and if it gets into your engine it can be a rebuild or replacement, if you are lucky it may just be a clean out...... etc etc"

Cheers
